Activist and former NFL player Colin Kaepernick accused American police officers of committing the “lawful lynching of black and brown people” Saturday.

AP News reports that Kaepernick made the comments while accepting an “Ambassador of Conscience Award” from Amnesty International.

“Racialized oppression and dehumanization is woven into the very fabric of our nation — the effects of which can be seen in the lawful lynching of black and brown people by the police, and the mass incarceration of black and brown lives in the prison industrial complex,” he said.
